In the pandemic and aftermath of the global financial crisis, interest rates in Europe and the United States, as well as in Japan, have fallen to extremely low levels (even negative rates). Why are interest rates in these countries at such low levels? Which statement is NOT correct?

A. All these countries have been experiencing very high inflation. Investors have concern about the high inflation and hence supply less loanable funds.

B. Large investors and banks found it more convenient to hold Treasury bills because they are stored electronically. For that reason, investors and banks were willing to accept negative interest rates.

C. All these countries have also been experiencing very low economic growth rates. The wealth declines lead to the reduction of loanable funds supply. The lack of profitable investment opportunities leads to the reduction of loanable funds demand.

D. Low and even negative inflation raises the supply of loanable funds and causes the demand of loanable funds to contract.
